To let a diversity of people dance to the same, simple tune reveals so much of their personal moods, yet by switching from one to another you can see the beauty of it all. To make it happen in different places tells you more about local atmosphere: where do passersby join the dance, where do they just look, where do they start to smile at the unexpected sight?

I guess what makes improvised dancing beautiful has something to do with its closeness to everyday life: based on repetitive moves and variations, it could go on eternally. And enjoyably so.
